LUMBER-PILER.

'PT-CIICATEON forming part of Letters Patent No. 321,348, dated June 30,1885.

Application filed February 2, 1885. (No model.)

T all whom it 71mg/ concern: l

Be it known that I, CARLOS E. DUNSHEE, of the city of Chicago, in thecounty of Cook and ,State of Illinois, have invented certain new anduseful Improvements in Lumber- Pilers, of which the following is adescription, reference beinghad to the accompanying drawings, in which-Figurel is a side elevation of my improved lumber-piler. Fig. 2 is anend View of the same. Fig. 3 is a top view of one of thecylinders,hcreinaftcr described, which are mounted upon the car. Fig. etis a crosssection of one of the upright posts, and Fig. 5 is a detailedview of the operating devices attached to the central upright.

The piling of lumber, especially in lumberyards where, because of lackof ground, the piles must be made very high, is a difficult andexpensive operation,and adds very materially to the cost of the lumber.

The object of my invention is to provide a novel combination ofmechanism whereby lumber may be rapidly and regularly piled and to anyreasonable height.

To this end it consists in the construction and combination of partshereinafter described, and definitely pointed out in the claims.

In the drawings, A A' A2 A3, Snc., represent upright supports or posts.These uprights I prefer to make in parts or sections of about ten feetin length. The uprights A A', 85e., are six in number, three in frontand three behind. The transverse distance between the posts I prefer tomake about Atwelve feet and the longitudinal distance about sixteenfeet; but these distances are not material, and depend upon the size ofthe lumber it is desired to handle. The sections c a are joined togetherby means of the metal caps c a,which are bolted securely to the ends ofsaid sections, as shown. When the posts are placed in position,they aresecured by the braces B B',&c., bolted or otherwise fastened thereto.

The inner face of each of the posts A A', d'0., is provided with a T-shaped groove, c2, extending from top to bottom. Nithin these groovesplay the ends of the cross-beams C C C, the center beam beingnecessarily bent, as shown in Fig. 2, which beams extend transverselyacross from one upright to the other.

I) D represent rails or traelrs,wl1ieh are secured to said cross-beams Cat appropriate distances from the uprights A A', 85e.

Fixed to each ofthe uprights A A', fue., near the foot thereof, arebearings in which the transverse shafts E revolve.

Mounted upon each of the shafts E,near the inner faces of each of theuprights A A', die., are the two drums c', as shown in Fig. 2, and uponone of the outer ends of said shaft E are mounted the beveledgear-Wheels c. The shaft F is mounted at right angles to the shaft Einbearingsf, attached to each of the three front posts, as shown in Fig.I,Which shaft F bears the beveled gear-wheels f' f f', which mesh eachwith one of the gears c upon the shafts E, so that a revolution of oneshaft causes a like revolution of all.

At the top of each upright A A', Src., are fixed the sheave pulleys G G'Gi, 81e., as shown. A wire rope or cable. g, is secured to each end ofeach of the cross-beams C, passes up over the sheave G, and then down,and is fastened to the drum e'.

The means for revoivingv the shafts E are preferably secured to themiddle upright A, and consist in the following to Wit: 'Vithin bearingsh 71.', attached to said upright A, is mounted the shaft H. This shaft Hhas mounted upon it the ratchet -whecl h2, the sprocketwheel h3, and thecrank or driving wheel hi. Upon the shaft li, mounted upon said uprightA, is a sprocket-wheel, ci, which is connected with the sprockebwheel h3by the drive-chain J. It is evident, therefore, that a revolution of theshaft H, Whether imparted by hand or in Whatever manner imparted,causes, through the instrumentality of the sprocket-wheels 72?' and eland drivechain J, a revolution of the transverse shaft E,to which saidsprocket-Wheel e'l is attached, and this, as before explained, revolvesthe two other transverse shafts E. By thcsemeans the drums e' Wind upthe ropes g, and thus raise the cross-beams C and tracks D to anydesired height, and the ratchet Il. holds the same in that position.

Upon the tracks D D a car, K, is run,ashere inafter described. This carK consists of a light frame mounted upon trucks, asshown.

The Vcylinders M M are mounted in bearings upon the frame of the car ateach end thereof.

IOO

These cylinders M M are mortised, as shown in Fig. 3, and through thesemortises the bent bars or hooks m pass and are sustained by thebolt-heads m at their upper ends. Attached rigidly to the upper sides ofthe cylinders M M are the arms m2 and m3, respectively.

At or near the center of the car atransverse shaft is mounted inbearings Z, which shaft has fixed rigidly at or near its center the armL,

extending on both sides of said shaft. The arm Z is also fixed to saidshaft near the end thereof, as shown. The arms m2 m3 are connected withthe opposite ends of the arm L in such a manner, as shown, that when theshaft to which the arm L is attached is revolved the two cylinders M Mare each revolved in the opposite direction.

Attached to the side of the frame of the car K is the bent arm 7c, whichsupports a swiveled pulley, 7c".

Bolted to the rail D upon its under sideand inclining away from therail, so as not to interfere with the movement ofthe car K, isa bentarm, N, also bearing a swivel-pulley n.

A cord, a', is fastened to the arm Z and passes over the pulleys k and nand down within reach of the operator, whostands by the central uprightA.

The arms P P/ are bolted to the under side of the rail D,and bear thesheaVe-pulleys p p', respectively. The ropes p2 and p3 are attached toopposite ends of the car K, as shown, and pass over the pulleysp and p'down within reach of the operator.

The depending arms R are fastened to the cross-beam r of the car K,slightly upon a slant to the perpendicular, and shape the end of thepile of lumber.

The operation of the device is as follows: The lumber which it isdesired shall be piled is laid on horses, one course or more at atime,between the posts A and A. rl`he cross bars C C C are now allowed todescend, carrying with them the tracks D D and car K. As the car is thusdescending the cord n is pulled upon, thereby turning the cylinders M M.This turns back the hooks m, so they will clear the ends of the boards.When below the level of the boards the cord is released and the hooks mare perlnitted to resume their normal position, as shown in Fig. l,below the boards, which they will do by reason of their own weight. Thepower is now applied to the crank or driving-wheel, and, as before eX-plained, the drums c wind the ropes g about thelnselves, therebyelevating the cross-beams C, tracks D, and car K, carrying the course ofboards. Vhen they are at the properheight, so that the boards are abovethe level of the pile of lumber, the cord p is pulled upon, which pullsthe car over the lumber-pile until the arms R strike against the face ofthe pile. Then the operator pulls upon the cord n', which, as beforedescribed, turns up the hooks m and dropsV the boards upon the pile. Thecordp2 is pulled upon by the operator, which drives the car back to theposition as shown in Fig. l, when the operation just described may berepeated until the pile has reached the desired. height. Y Y

The bearings in which the roller Mis mounted may be moved along theframe of the car as desired, and bolted at any point so as to take inany length of lumber.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent7 is- 1. In alumber-piler, thecombination ofupright supports, sheaves mounted thereon at or near their tops,transverse shafts mounted thereon near their feet, drums mounteduponsaid transverse shafts, and alongitudinal shaft mounted in bearingsattached to said upright supports and geared to said transverse shafts,with transverse cross-beams, tracks mounted upon said cross-beams,cables attached to said cross-beams, passing over said sheaves, andattached to said drums, and means for rotating said shafts,substantially as and for the purpose set forth.

l2. In alumber-piler,the combination of vertically-adjustable tracks anda car adapted to run on said tracks, and mechanism whereby the car ismoved along said tracks, with depending hooks mounted upon said car andmeans for swinging said hooks in contrary directions, substantiallyasand for the purpose set forth.

3. In a lumber-piler, the combination, substantially as set forth, ofvertically-adjustable rco tracks, a car adapted to run upon said tracks,

two mortised cylinders mounted in bearings upon said car, hooks whichoperate in said mortises, the arms M2 M3, attached to said cylinders, atransverse shaft mounted near the middle of said car,the arms L Z,attached thereto, rods connecting the arms M2 M3 and arm L, the arm k,and swivel-pulley 7d, with the arm attached to the track, theswivel-pulley n, and cord n', for the purpose specified.

4. In alumber-piler,the combination of vertically-adjustable tracks anda car adapted to run on said tracks with the pulleys p p', fastened tothe under side of said tracks, and the cords 292113, attached to saidcar and passing over said pulleys, substantially as described, and forthe purpose set forth.

5. In a car adapted to run on vertically-adjustable tracks, theYcombination of two mortised cylinders mounted upon said carl and hooksoperating in said mortises, and means for producing-a.v partialrevolution of said cylinders in opposite directions, with depending armsattached to one end of said car, substantially as and for the purposeset forth.
